Anatoly: I will try your approach:
Same problem I can address in a different way.
Suppose the energy is not linear in case of a Pt-L3 scan.
We can set Pt-L3 edge at known 11564 eV. Scanning all the way to
L2 edge and say we find it 200 eV off (exaggerating), can we set
in Athena the L2 edge at known 13273 eV, while the L3 edge is still
at 11564 eV?

Is it possible in Athena to change the y-axis (energy scale) at two different energy points of an EXAFS scan?
I have a Ni foil spectrum as a function of time. The edge can be set at 8333.0 eV, and I want to to assign higher energy to a known feature in the Ni scan.
I am not 100% certain I understand the question, but I think the
question is about the calibration dialog. That is, you want to assign
an energy shift, but not referenced to the edge energy position.
Why can't you just set the energy shift by hand on Athena's main page?
